CAR-DUMPING MECHANISM.

Specification of Letters Patent.

Patented Oct. 8, 1.912.

Application led October 30, 1911. SeriaLNo. 657,691.

T o all whom it 'may concern:

Beit known that I, Kiln. lil. HANsnN, a subject of Germany, citizen ofthe United States, and resident of Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefullmprovement in Car-Dumping Wechanism; and I do hereby declare thefollowing to be a full, clear, and exact description thereof.

My invention relates to dump cars.

The object of my invention is to provide a dump car in which provisionis made for allowing a larger travel than is ordinarily obtained of thatside of the car opposite that to which the car is dumped, so that thecar when dumped is brought closer to the ground and there is a greaterangle of inclination in side dumping which greatly facilitates thedischarge of the material from the car.

To these ends my invention comprises' the novel features hereinafter'set forth and claimed.

In the accompanying drawings Figure l is a side elevation of my improveddump car; Fig. 2 is a plan View, 'a portion of the car being removed;Fig. 8v is a cross section; and lFig. 4 a like view showing the car indumping position.

Referring to the drawings, the numeral 2 designates a suitable car bodywith sides 3 which are removable or may be swung up out of the way whenthe contents are to be discharged from the car. The center-- sills atare formed of channel-bars of the usual construction, and engaging saidcenter-sills are the trunnion castings 5 which rest upon the castings 6and upon which said trunnions are adapted to rock when the car is tiltedto one side or the other. The castings G have t-he central depression 7to receivey the central portion S of the trunnion and said casting hasthe upwardly projecting side portions 9 which are engaged by the sidesofv the trunnion in dumping and prevent the trunnion from slipping fromthe support or casting G. The cast-ing G 1s carrled by the pedestal 10which is carried on the sub-structure 11 which may be of any suitableconstruction. This sub-strucf ture l'l carries the cylinders 1Q and 13,said cylinders having the inlets 14 for the admission of air or othermotive fluid to operate the same. Within the cylinders are the pistons15 to which the rodsI or links 16 are secured. The upper ends of thepiston 1G are connected to the crank-arms 1T. These crank-amis 17 aresecured to theshaft 18 extending longitudinally of the ear. The arms 19are likewise` seellred to the shafts 1S and said arms carry the sheaveor rollers Q0. Chains 23 and 124-. are secured to the stationarybrackets 25 at opposite sides thereof, and the other ends of said chainsare connected to the car body, as at 20, said chains engaging thesheaves Q0. (`ables or other flexible cords may be employed.

In the operation of my invention, when it is desired to dump the car tothe position indicated in Fig. 4, air is admitted to the cylinder 13 andthe piston l5 is raised therein. The arm 1G will move the crank-arm 17,and said crank-arm being secured to the shaft 18 will rock said shaftand move the arm '19 downto the position indicated in Fig. 4:. Thismovement of the arm 19 will act to lower that side of the car, the cartilting on the trunnion-support 6. As the chain 24; is secu red to thebracket 25 and to the earbody, it is apparent that the lowering of thearm 19 will cause the sheave to travel along the chain to the positionindicated in Fig. 4. lVhen the car is dumped in this manner the chain 23at the opposite side will pull `on the arm 1.9 and more said arm up to asubstantial vertical position at the same time rocking the shaft 1S andmoving the piston 15 in the cylinder 12 down to the lower end of saidcylinder. The chain Q3 thus provides the slack to compensate for a muchlarger travel on that side of the car and consequently a greater dumpingangle is obtained, which increases the facility for discharging thematerial from the car. l `urthermore the chains 23 and 24 hold the carin position against accidental dumping, and l am enabled to dispensewith the rigid lever connections with the car-body which do not permitof the same flexibility of movement as I obtain by the employment of thechains arranged in the manner set forth.

The most advantageous location for the securing of the chain to thecar-body, is over or substantially over the sheave and the point ofconnection with the bracket should be located as close to the center ofthe rota tion of the dumping body as possible to get the best results. ldo not, however,

confine myself to the exact location of these tion.'

points of connection, as they maybe. varied and still come within thescope of my inven- When the car is in the dumping position as indicatedin Fig. 1, and it is desired to bring it back into its normalposition,-air is admitted in the cylinder 12 and 4the piston therein israised whereby the shaft 13 is rotated to lower the arm 19 to thepositionindicated in Fig. 3 whereupon the car is brought around vto itshorizontal position' andthe parts at the .opposite side also resunietheir normal positions with the'chaink in position to'hold the cati`against accidental dumping..

By my invention, I 4provvide a dumping-` mechanism whichl is adapted forcars of great length, as lthe dumping act-ion takes place uniformly atallpoints. and any strain or twisting action is entirely obviated. WhatI claim is: f

1. Ina dump-car, the combination of the tilting car-body, an underframesupporting said tilting car-body, chains vconnected at one of their endsto the car-body and at their opposite ends to .the underframe, membersmovably engaging said chains, and mechanisin for operating said membersto tiltsaid car-body.

2. In a dump-car, the combination` oi a tilting car-body, anunderframe'supporting.

,lever arms, sheaves on said arms engaging said chains, and mechanismfor moving said arms to ytilt said car.

4. In a dump-car, the combination of a tilting car-body, an underi'ramesupporting same, chains connected at one of their ends vdump saidcar-body.

5. In a dump-car, the combination of a tilting'- body, an underframesupporting same, chains connected at one of their ends to saidunderframe and at their opposite "ends to the .car-body, pivo-tallymounted lever arms, sheaves on said arms engaging with said chain, afluid operated cylinder, and connections between said arms and saidcylinder for moving `the arms.

6.In a dump-car, the combination of a tilting car-body, an underframesupporting same, chains connected to said underframe and car-body,movable arms, sheaves on said arms engaging said chains, a shaft onwhich said arms are mounted, a fluid operated cylinder, and connectionsbetween said cylinder rock the same to raise and and said shaft to lowersaid arms.y Y

7. In a dump-car, the combination of a tilting car-body, an underframesupporting same, chains connected to said underframe and .car-bo`dy,arms, sheaves on said arms engaging said chain, a shaft on which saidarms ,are mounted, crank-arms von said shaft, a fluid operatedcylinderand connections between said crank arms and cylinder foroperating said tirst named arms.

8. In a dumping car, the combination of a tilting car-body, anunderframe su porting same, chains connected to said un erframe andthecar-body, movable arms, sheaves on said. arms engaging said chains, afluid op erated. cylinder, connections between said' cylinder and saidarms for operating same, two-or more of said arms being connected t'ooperate simultaneously.

In testimony whereof, I the said KARL H. HANSEN have hereunto set myhand.
